UL Listing Information

The Control Techniques UL file number is E171230. Confirmation of UL listing can be
found on the UL website: www.ul.com.
Common UL information
Conformity
The drive conforms to UL listing requirements only when the following are observed:
• The drive is installed in a type 1 enclosure, or better, as defined by UL50
• The ambient temperature does not exceed 40°C (104°F) when the drive is
operating
• The terminal tightening torques specified in section 10.2 on page 288.
• If the drive control stage is supplied by an external power supply (+24V), the
external power supply must be a UL Class 2 power supply
Motor overload protection
The drive provides motor overload protection. The default overload protection level is no
higher than 150% of full-load current (FLC) of the drive in open loop mode and no higher
than 175% of full-load current (FLC) of the drive in closed loop vector or servo modes. It
is necessary for the motor rated current to be entered into Pr 0.46 (or Pr 5.07) for the
protection to operate correctly. The protection level may be adjusted below 150% if
required. Refer to the Unidrive SP User Guide for more information. The drive also
provides motor thermal protection. Refer to the Motor thermal protection section of the
Unidrive SP User Guide.
Overspeed Protection
The drive provides overspeed protection. However, it does not provide the level of
protection afforded by an independent high integrity overspeed protection device.
Power dependant UL information
Unidrive SP size 1 to 6
Conformity
The drive conforms to UL listing requirements only when the following is observed:
Fuses
Size 1 to 3
• The correct UL-listed fast acting fuses (class CC up to 30A and class J above 30A),
e.g. Bussman Limitron KTK series, Gould Amp-Trap ATM series or equivalent, are
used in the AC supply. The drive does not comply with UL if MCBs are used in place
of fuses.
For further details on fusing, refer to section 10.1 on page 283.
Size 4 to 6
• The UL-listed Ferraz HSJ (High speed J class) fuses are used in the AC supply. The
drive does not comply with UL if any other fuses or MCBs are used in place of those
stated.
For further details on fusing, refer to section 10.1 on page 283.
